Roadkill Hotspot
A roadkill hotspot or blackspot is an accumulation of roadkill along a given length of roadway with significantly more wildlife-vehicle collisions than expected to occur by chance, based on a normal distribution. Decision-makers can then authorize the construction of roadkill mitigation infrastructure based on roadkill hotspot locations, prioritizing those with the most roadkill in number or those for a particular target species for conservation. Roadkill hotspots vary spatially and temporally, depending on the scale, duration of monitoring, and both the species and season in question. They can be calculated using roadkill survey data; GPS coordinates of roadkill collected by researchers and highway maintenance personnel, or increasingly, civilian-reported data. Additionally, roadkill hotspots can be projected by using a model to ascertain probable locations; models typically use existing wildlife abundance, distribution, and mitigation data combined with landscape variables (distanc ...

Roadkill
Roadkill is a wild animal that has been killed by collision with motor vehicles. Wildlife-vehicle collisions (WVC) have increasingly been the topic of academic research to understand the causes, and how they can be mitigated. History Essentially non-existent before the advent of mechanized transport, roadkill is associated with increasing automobile speed in the early 20th century. In 1920, naturalist Joseph Grinnell wrote of his observations in the state of California that "this is a relatively new source of fatality; and if one were to estimate the entire mileage of such roads in the state, the mortality must mount into the hundreds and perhaps thousands every 24 hours." In Europe and North America, deer are the animal most likely to cause vehicle damage. Causes The development of roads affects wildlife by altering and isolating habitat and populations, deterring the movement of wildlife, and resulting in extensive wildlife mortality. One writer states that "our insulate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildlife Crossing
Wildlife crossings are structures that allow animals to cross human-made barriers safely. Wildlife crossings may include underpass tunnels or wildlife tunnels, viaducts, and overpasses or green bridges (mainly for large or herd-type animals); amphibian tunnels; fish ladders; canopy bridges (especially for monkeys and squirrels); tunnels and culverts (for small mammals such as otters, hedgehogs, and badgers); and green roofs (for butterflies and birds). Wildlife crossings are a practice in habitat conservation, allowing connections or reconnections between habitats, combating habitat fragmentation. They also assist in avoiding collisions between vehicles and animals, which in addition to killing or injuring wildlife may cause injury or death to humans and property damage. Similar structures can be used for domesticated animals, such as cattle creeps. Roads and habitat fragmentation Habitat fragmentation occurs when human-made barriers such as roads, railroa ...

Siriema Hotspot Output
The seriemas are the sole living members of the small bird family Cariamidae (the entire family is also referred to as "seriemas"), which is also the only surviving lineage of the order Cariamiformes. Once believed to be related to cranes, they have been placed near the falcons, parrots, and passerines, as well as the extinct Phorusrhacidae (terror birds).Hackett, S. J. ''et al''. (2008) A Phylogenomic Study of Birds Reveals Their Evolutionary History. ''Science'' 320(5884):1763–1768 The seriemas are large, long-legged territorial birds that range from in length. They live in grasslands, savanna, dry woodland and open forests of Brazil, Bolivia, Argentina, Paraguay and Uruguay. There are two species of seriemas, the red-legged seriema (''Cariama cristata'') and the black-legged seriema (''Chunga burmeisteri'').del Hoyo, J. Elliott, A. & Sargatal, J. (editors).

Anthropogenic Effect
Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. The term ''anthropogenic'' designates an effect or object resulting from human a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
